ABSTRACT

This study investigates how object affordances modulate approach and avoidance behaviors in virtual reality (VR). The primary hypotheses are that 1) motivational relevance shapes facilitation or inhibition of behaviors while interacting with virtual objects, and that 2) approach-avoidance can be quantified using spatial and temporal aspects of behavior in VR. An experiment was conducted to track and examine user behaviors during a virtual photo-sorting task that used images with varying valence and arousal levels. Spatial indicators of approach and avoidance were operationalized as the distance between the individual and the photo during the task. Temporal indicators were operationalized as the speed and latency of gazing at the objects, selection order, and sorting behavior. Results show that stimulus valence and arousal significantly affect speed and latency during object selection, demonstrating motivational reactions to virtual objects. Exploratory analyses also revealed varying patterns of object selection across individuals. Overall, this study has implications for the design of virtual environments and supports the use of VR technology in studying motivational processes and behaviors relevant for media psychologists.

摘要

本研究调查对象可供性如何调节虚拟现实 (VR) 中的接近和回避行为。主要假设是 1) 动机相关性在与虚拟对象交互时塑造促进或抑制行为，以及 2) 可以使用 VR 中行为的空间和时间方面来量化接近-回避。进行了一项实验，以跟踪和检查虚拟照片分类任务期间的用户行为，该任务使用具有不同效价和唤醒水平的图像。接近和回避的空间指标被操作为任务期间个人与照片之间的距离。时间指标被操作为注视对象的速度和延迟、选择顺序和排序行为。结果表明，刺激效价和唤醒显着影响对象选择过程中的速度和潜伏期，展示了对虚拟对象的动机反应。探索性分析还揭示了个体之间不同的对象选择模式。总体而言，这项研究对虚拟环境的设计有影响，并支持使用 VR 技术研究与媒体心理学家相关的动机过程和行为。
